ReaXus LS Class
High Performance Isocratic Pumps
The reliable ReaXus LS Class consists of single-headed, positive displacement piston pumps incorporating advanced cam designs for very low pulsation.
The pumps are ideal for a wide variety of applications, Semi-Prep LC, metering & dispensing, and general laboratory use. Standard fluid path materials are Stainless Steel with PEEK options. Other available features include jacketed heads for temperature controlled processes. With 5 mL/min, 10 mL/min, and 40 mL/min versions available, and pressure capability up to 6,000 psi, these versatile pumps will meet the most demanding applications.
Features include automatic pressure compensation, Pulse Dampener, integrated Prime-Purge Valve, interactive keypad control, and complete PC control and status through RS-232 and Micro USB 2.0 ports. The unique LS Class provides the highest performance/cost ratio in a compact package.
